Embodiment Construction
[0040] As described in the background art, there is a limitation in forming an ITO film on the side of the glass substrate facing away from the optical glue. Therefore, the inventors set the ITO film on the side of the glass substrate facing the optical glue and used the following method Prepare wafer-level optical lens (WLO), as follows: figure 1 As shown, first, a circular glass substrate 10 is provided. An ITO film layer is formed on the glass substrate 10, and the ITO film layer includes at least two ITO pads 20; then, on the glass substrate 10 The side with the ITO film layer is covered with a layer of optical glue 30; then, the optical glue 30 is pressed by a mold; then, the optical glue 30 is cured by UV (ultraviolet light) and / or thermally baked 30 Perform curing treatment; finally, remove the mold. Since all the optical lens modules of the wafer-level optical lens in the above process are prepared through an integrated molding process, the ITO film is completely confin...
